LOL

I installed a new windows 11 yesterday on a fairly powerful machine, everything lags so much on a brand new install it's unreal. Explorer takes ~2-3 seconds to be useable. Any app that opens in the blink of an eye under Linux on the same machine takes seconds to start. Start menu lags. It's just surrealistic. People who say these things work just have never used something that is actually fast.
